Correct Matching
| # | Term | Definition |
|---|---|---|
| 1 | Inbreeding | Mating of related individuals (increases homozygosity) |
| 2 | Outbreeding | Mating of unrelated individuals (increases heterozygosity) |
| 3 | Panmixia | Random mating |
| 4 | Grading up | Pure-bred is obtained (after 7–8 generations of mating local females with pure-bred sire) |
| 5 | Cross breeding | New breed is evolved by mating animals of different breeds within same species |
Note: Inbreeding is also known as genetic assortative mating; outbreeding is known as genetic disassortative mating.
